So over the last 6 tanks of fuel I have been using Redline SI-1 instead of my normal Lucas UCL with my Shell Top-Tier fuel (usually E-10) and I have noticed a much better response from my engine, a slight increase in average mileage (nothing to write home about).
I think I'm going to keep using it instead of Lucas UCL or anything else. I'm using 1/4 of the bottle for each tank of fuel (72L) and that seems to be the sweet spot for me.
I have used SI-1 in the past to clean up an engine but found Amsoil PI to be slightly better but in terms of a regular fuel add and UCL I really like the SI-1 and it's much cheaper than the Amsoil PI which isn't for regular additions to the fuel.
Your thoughts?
